Project Gravitaur is a documentary film production project centered on Bob Lazar's description of the S-4 facility at Papoose Lake. The project's principal film, titled S4 (also referred to as S4: The Bob Lazar Story), was announced in late 2023 for a 2024 release, delayed through 2025, and began public circulation around mid-2025.
Virtual reality reconstruction
A central production element is a detailed virtual reality reconstruction of S-4, including the nine hangar bays, the recovered disc craft Lazar worked on (the "Sport Model"), and the adjacent propulsion laboratory spaces, enabling viewers to experience the facility in first-person perspective.
Release and reception
After its announced 2024 release date slipped, fan channels reported continued production delays through September 2025. Viewer reactions from late 2025 were mixed, with criticism focused on the opening minutes of the film but broadly positive reception of the VR reconstruction and of the documentary's substantive content.
